Kendrick Lamar recently addressed the feud in an interview with Rolling Stone, claiming he wasn't even aware of it when he joined forces with Swift on a "Bad Blood" remix — a track widely believed to be about Swift's former friendship with Perry. Despite appearing alongside Swift in the track's video, Lamar opted out of picking a side. "That's far beyond my concern," he said. "I have to stay away from that, for sure. That's some real beef."
